Shortly before Diablo III's console release, it looks like Blizzard has something up their sleeves for the title, which has yet to see an expansion pack. After recently trademarking 'The Dark Below,' a teaser site opened today with little else to see but a faint background and a Book of Tyrael quote... but the Diablo font is unmistakable, as is the trademark listed near the bottom.

President Michael Morhaime had recently promised a Diablo-related announcement at the upcoming gamescom event in Germany. Could Diablo III be getting a (rather morbid) expansion in the near future?

The PS3 and Xbox 360 versions of Diablo III will release on September 3rd.
